# Qual O Próximo Número Da Sequência a Frente: 1, 3, 6, 10, 15, 21, 28, …

Sequences are a great way to understand and predict patterns. In this article, we’ll look at the sequence of numbers 1, 3, 6, 10, 15, 21, 28, and determine the next number in the sequence.

## Identifying the Pattern

The first step in determining the next number in the sequence is to identify any patterns that exist. In this sequence, it is easy to see that each number is the sum of the two numbers that came before it. For example, 10 is the sum of 3 and 6, and 15 is the sum of 6 and 10. This pattern continues for the entire sequence.

## Predicting the Next Number

Now that we have identified the pattern, we can use it to predict the next number in the sequence. To do this, we simply add the two numbers that came before it. In this case, the two numbers are 21 and 28. If we add them together, we get 49, which is the next number in the sequence.

By understanding the pattern in the sequence, we were able to predict the next number in the sequence. Knowing the patterns in sequences can be a great way to understand and predict the future.
The sequence of numbers 1, 3, 6, 10, 15, 21, 28 and so on is part of something known as an arithmetic sequence. An arithmetic sequence is a sequence of numbers where each number is the previous number plus a common difference. In the case of this particular sequence, the common difference is +2. This means that the next number in the sequence will be the previous number plus two, thus the next number in this sequence is 36.

Arithmetic sequences are used in a variety of ways in math and also in everyday life. For instance, they can be used to find the amount of money in an investment if its gains increase at a constant rate, or in a more basic sense when counting the change in your pocket. No matter the application, understanding how a sequence works can be incredibly helpful.

When it comes to working with arithmetic sequences, a simple rule to remember is that if you know the first number in the sequence (a1) and the common difference (d) then to calculate the nth term, which is essentially the nth number in the sequence, you simply use the formula an = a1 + (n – 1)d. So for this example, a1 is the first number in the sequence, which is one, and the common difference is two. Plugging that information into the formula, we get that the next number in this sequence must be 36, which is calculated as 1 + (8 – 1)(2).

The arithmetic sequence provides an easy and straightforward way to calculate the next number in a series of numbers that are all increasing by a constant amount. Whether you’re counting change in your pocket or calculating a future value of an investment, understanding how arithmetic sequences work and the formulas used to calculate the next term in a sequence can be incredibly helpful.
